The International Effects of the Fed's UMP

Hi! This page is still in development. Thanks for your patience!

Introduction

This is a friendly (updated) version of my undergraduate thesis. In this project, I estimate a traditional VAR with exogenous variables to investigate the international effects of the implementation of unconventional monerary policy tools on the Mexican Economy, namely the Forward Guidance and the Quantitative Easing. You can see the python code in this Jupyter Notebook.

What does Unconvetional Monetary Policy mean?

First, we need to state what the Federal Reserve (the Fed) is, why it is important and then how it relates to the Monetary Policy. Well, with the risk of oversimplifying, the Fed is in charge of two things: reaching maximum employment and keeping stable prices (low inflation). This is also known as "dual mandate." The set of tools that the Fed can use to reach its objectives is calles the Monetary Policy.

Now, if there's an Unconventional Monetary Policy, that implies that there's also a Conventional Monetary Policy. The "Conventional" Monetary Policy is the set of tools that the Federal Reserve usually applies to reach its goals. That's basically the short term interest rate. The Fed buys and sells short term government bonds to influence its prices and therefore their interest rate. When the short term interest rate moves, it generates a chain reaction in the financial system that spreads through several channels and into the real economy.

But, what happens when the interest rate is really close to zero? This situation was believed to be the limit of the monetary policy tools to influence the economy. When the interest rate reached the zero lower bound (ZLB) during the Great Financial Crisis, the unconventional monetary policy (UMP) made its appearance.

This new tool (at least for the Fed) allowed the Federal Reserve to buy not only short term bonds, but also long term bonds and virtually any asset class. So it wouldn't influence only the short term interest rate, but also longer parts of the interest rate curve. This received the name of "Quantitative Easing" a.k.a. throwing money from helicopters (figuratively). In addition, the announcements made by the Fed contained information about the future monetary policy decisions with the objective of manipulating the market expectations about the future interest rates. This one is called "Forward Guidance."

Those are the two main tools of Unconventional Monetary Policy.

How can we measure these effects?
